Are you talking about using root access to the server in SSH (Secure Shell)? Or looking at CSF/LFD logs in WHM?

To see logs at these points, you need root access. Use strong passwords. Use keys in SSH instead of passwords.

If a hacker gets root access, he can do anything. Anything.

If you're logging in with some other user and can see those logs, you need to check your security, permissions and other settings. My "wheel group" user can list the files in /var/log, but cannot see any of the "important" ones, unless I sudo to root.

/var/cpanel/ is even more restrictive, at least on my server. Must be root to even see it.

If you take the root user's ability to use functions, like ls, cat, echo, etc, be warned: you'll probably screw up your installation--especially the ability for scripts to run.
